Title: Black level detecting circuit of video signal
Inventor: TAKESHIMA MASAHIRO
IPC: H04N5/20
Filed: 1998-03-02
Abstract: The invented black level detecting circuit compares an input video signal with a current minimum value of input video signals, and then calculates a difference between the input signal and the current minimum value when the input value is smaller than the current minimum value, and then outputs the calculated difference only during a detecting period of the black level. Subsequently it corrects the minimum value by using this output for renewing the current minimum value, and finally outputs this renewed minimum value as a new minimum value of the input video signal. The black level detecting circuit also latches the minimum value during the vertical blanking pulse and initializes the minimum value during a vertical blanking period so as to detect a black level of the input signal. As such, the black level detecting circuit measures the black level only during a video period, thereby reducing detection errors due to noises, and also an automatic initialization of the minimum value during a blanking period can contribute to a more stable detection of the black level. The black level detected can be used effectively as a control signal over picture quality for each field or each frame.
